Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass substrate processing and manufacturing, in particular to a glass positioning correction device. Background Art

[0002] In the glass processing industry, the performance and precision of the grinder, as a key equipment, directly affect the quality and pass rate of the final product. In the operation process of the grinder, the glass positioning device plays a vital role. It is not only responsible for accurately fixing the glass to be processed to ensure the stability of the processing process, but also undertakes a number of key monitoring and adjustment functions. Specifically, the device uses high-precision measurement technology to monitor the integrity of the incoming materials (to prevent breakage), dimensional changes, and squareness deviations in real time. As a core component for controlling the stability of chamfering processing, it plays an irreplaceable role in improving product processing accuracy and consistency.

[0003] However, although the existing glass positioning devices can effectively perform their intended functions in most cases, they are still insufficient when faced with specific challenges. A significant problem is that when the incoming glass has abnormal squareness or slight deviation, the traditional grinding process often has difficulty in directly identifying and correcting these deviations, resulting in the processed glass products still retaining the original defects, which in turn causes batch defects and seriously affects production efficiency and product quality. This problem not only increases the cost of subsequent inspection and rework, but also has a negative impact on brand image and customer satisfaction. Utility Model Content

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: a glass positioning and correction device, which is composed of a servo rotation module 1, a first servo driving module 2, a second servo driving module 3 and a positioning and measuring module 4. Before the glass 5 is placed on the upper grinding machine, it needs to be placed on the servo rotation module 1 first. Because after the glass 5 is placed on the servo rotation module 1, there will be problems such as incoming material offset and abnormal incoming material straightness angle, so it is necessary to position and correct the glass 5. Therefore, after the glass 5 is placed on the servo rotation module 1, the first servo driving module 2 will drive the overall movement of the second servo driving module 3 and the positioning and measuring module 4 to directly above the glass 5. Subsequently, the second servo driving module 3 drives the positioning and measuring module 4 to descend. After the positioning and measuring module 4 descends to the same horizontal plane as the glass 5, the positioning and measuring module 4 positions and measures the glass 5. According to the measurement results, the servo rotation module 1 drives the glass 5 to rotate to ensure that the position of the glass 5 on the grinding machine workbench meets the processing requirements;

[0026] Specifically, the servo rotation module 1 includes a base 11, the top of the base 11 is rotatably connected with a vertical shaft 12, the outside of the vertical shaft 12 is installed with a driven gear 13, the top of the vertical shaft 12 is installed with a loading platform 17, the side of the driven gear 13 is meshed and connected with a driving gear 16, a driving motor 14 (the driving motor 14 is a servo motor) is installed on the outside of the top of the base 11, the driving end of the driving motor 14 extends to the inner side of the top of the base 11, and is connected to the driving gear 16 through a reducer 15, and a plurality of evenly distributed supporting brushes 18 are installed on the upper part of the loading platform 17, and the plurality of supporting brushes 18 can jointly carry the glass to be tested;

[0027] When the servo rotating module 1 is working, the glass 5 is placed on a plurality of supporting brushes 18, and after being processed by the positioning and measuring module 4, the driving motor 14 works, and after passing through the reducer 15, it drives the driving gear 16 to rotate, and the driving gear 16 drives the driven gear 13 to rotate, and then drives the vertical shaft 12 to rotate in the base 11, and the vertical shaft 12 drives the loading platform 17 to deflect the corresponding angle, so that the glass 5 on the loading platform 17 rotates the corresponding angle, ensuring that the position of the glass on the grinding machine workbench meets the processing requirements;

[0028] The positioning and measuring module 4 includes a cross 41 installed at the driving end of the second servo driving module 3, and the ends of the cross 41 are respectively installed with a first positioning and measuring component 42, a second positioning and measuring component 43, a third positioning and measuring component 44 and a fourth positioning and measuring component 45 (the first positioning and measuring component 42, the second positioning and measuring component 43, the third positioning and measuring component 44 and the fourth positioning and measuring component 45 have the same structure), and the first positioning and measuring component 42, the second positioning and measuring component 43, the third positioning and measuring component 44 and the fourth positioning and measuring component 45 are respectively installed around the glass to be measured;

[0029] When the positioning and measuring module 4 is working, the second servo drive module 3 drives the positioning and measuring module 4 to descend to the same horizontal plane as the glass 5, and then the second positioning and measuring component 43 and the third positioning and measuring component 44 extend first to press against the two sides of the glass 5 to provide a positioning reference. After pressing against, the first positioning and measuring component 42 and the fourth positioning and measuring component 45 extend again to press against the other two sides of the glass 5. When the glass 5 is offset in the incoming material, after pressing in the above four directions, the glass 5 is positioned, thereby solving the problem of incoming material offset.

[0030] The first positioning and measuring component 42 includes a cylinder 421 installed at the end of the cross 41. A movable seat 422 is installed at the telescopic end of the cylinder 421 (the movable seat 422 is connected to the cross 41 through a linear guide rail). Positioning wheels 423 are rotatably connected to both ends of the movable seat 422, and a first measuring probe 424 and a second measuring probe 425 are respectively installed inside the two positioning wheels 423 at both ends of the movable seat 422;

[0031] When the first positioning and measuring component 42 is working, the cylinder 421 pushes the movable seat 422 to move towards the direction of the glass 5. If there is no problem with the incoming straight angle of the glass 5, at this time, the two positioning wheels 423 should be in contact with the glass 5 at the same time, and the detection ends of the first measuring probe 424 and the second measuring probe 425 are in contact with the edge of the glass 5 at the same time. At this time, the measuring distances of the two probes are both zero. Similarly, if there is a problem with the incoming straight angle of the glass 5 (as shown in the attachment Figure 6 ), at this time, only one of the positioning wheels 423 will be in contact with the glass 5, and the other one cannot be in contact due to the above problem. At the same time, only one of the probes is in contact with the glass 5 (in the figure, it is the second measuring probe 425 in contact, d1 is 0), then there will be a distance (d2 is not 0) between the other probe (the first measuring probe 424) and the edge of the glass 5. At this time, it can be known that there is a problem with the incoming straight angle of a certain edge of the glass 5. At this time, it can be corrected by the servo rotation module 1 to ensure that the position of the glass 5 on the grinding machine workbench meets the processing requirements.
